Some of the parasitic ants soon swarmed inside from the entrance and exit of the anthill they found, and after a long encounter with the defending Divine Envoy King warriors, a battle broke out between the two sides.

This kind of narrow indoor environment combat was originally beneficial to the Divine Envoy King Legion, which was good at razor tactics, and the power of razor tactics could be maximized in this kind of terrain where there was no need to worry about the threat of the side and rear only to face the enemy head-on. This is also why the protagonist dares to give up the first line of defense of the city wall and command the whole army to retreat.

In the past, whether it was against paving ants or hunting sickle ants, the Divine Envoy King's legion in indoor street battles always made the enemy pay a heavy price, and their own losses were insignificant, and sometimes the exchange between the two sides was as high as more than 100 to 1.

But this time, the Divine Envoy King's legion was facing parasitic ants.

In the previous battles with parasitic ants near [Dongyang City] and in the southern hills, the Divine Envoy King Legion defeated the enemy through field battles or outdoor defensive battles, and at that time, the difference in strength between the two sides was not large, and the Divine Envoy King Legion still had air superiority.

This time, in the face of the enemy army, which had a great advantage in strength and air supremacy, the Divine Envoy King's army had to retreat to the ant mound.

Unexpectedly, although the narrow combat environment is conducive to razor tactics, it is also conducive to parasites.

At several entrances and exits, fierce and brutal battles are staged.

I saw that the big-headed ant warriors of the Divine Envoy King Legion were arranged in an unusually tight formation in the narrow passage, huddled in front and back, and blocked the route of the parasitic ants who wanted to break through.

The parasitic ants opened their sharp jaws, and the wolves rushed forward suddenly, trying to kill the Divine Envoy King warrior in front of them.

But when they bite together with the jaw-to-jaw bite of the Divine Envoy King's warriors, they will always be condescendingly cut off by the Divine Envoy King's warriors who rush onto the backs of their companions. This is where the power of the razor tactic lies, each parasitic ant fights at the same time to deal with the counterattack of two or more Divine Envoy King Ant Warriors.

Soon the passage was filled with severed corpses, and the parasitic ants were not completely dead, their heads were still instinctively biting at each other, sometimes suddenly biting the limbs of allies or opponents, and then not letting go. What they exchange for the last ounce of strength before death is the damage to the opponent's arthropod, and this level of damage often means future disability, which can be seen in its ferocity.

And in the pile of corpses that almost blocked the passage, the silk thread parasite was shuttling like a spirit snake.

These silk parasites are not very fast, and if they are outdoors, their pale and translucent colors will refract a striking light from the background in the light, and with a slightly clumsy movement, any ant can easily dodge them. It can only rely on its ability to bewitch ants to infect ants.

But in the battlefield inside the anthill, in the gloomy and dark passage, there are not even fluorescent bacteria, and the body color of the silk parasite shows its adaptability, almost transparent, and in the passage, the corpses shuttle and swim like ghosts, crawling directly towards the defenders who have not yet realized the danger.

Soon, these parasites had climbed into the body of the front-line Divine Envoy King warrior little by little while the defenders were still concentrating on counterattacking.

Even if some silk thread parasites were discovered by the fighters in the second row, they pulled it down and chopped it up to kill. However, the vast majority of silk thread parasites are not eliminated in time.

It wasn't until a sharp tingling sensation came from his back that the Divine Envoy King warriors in the first row realized that they had been attacked.

But these unfortunate warriors didn't even have a chance to realize what they were attacking.

Some of the infected fighters, distracted by the severe pain, were seized by the stalemate parasitic ants on the opposite side, and were taken advantage of to bite the neck or head, and were quickly killed.

Although some survived the severe pain, the paralyzing fluid secreted by the silk thread parasite quickly flowed all over the body, and they soon fell down in a groggy state.

The defenders want to rescue their fallen comrades, but this is difficult to do in the heat of battle. Instead, the attacking parasites were able to advance with the help of the silk parasite, but they paid no attention to the infected who fainted to the ground.

These infected people have begun to exude a faint smell of parasitic ants, which will not kill them, and by the time they get up again, they have become them.

At this time, the roots of the silk parasite have taken firm root in its body, and the bifurcation of the silk thread is tightly entangled with the important nerves of the ant, and the nerve impulses generated by the silk parasite replace the control of its original brain, so that the infected ant can only act according to the intention of the parasite. At this time, the brain of the infected person is not dead, but the activity is inhibited by the anesthetic secreted by the silk parasite bacteria all the time, and it becomes a living dead ant.

The spores of the silk parasite can also infect the parasitic ants, absorb nutrients from their internal organs, thrive, slowly emerge from the internal organs, poke their heads out of the gaps in the carapace, slowly mature, and then break away after encountering a suitable new host, repeating the process.

Once a healthy ant is infected, it is enough to give birth to several new parasites that can quickly infect an entire nest.

At present, the Divine Envoy King Legion does not need to worry about the long-term infection of the silk thread parasitic bacteria, because it will take time, and what the Divine Envoy King Legion needs to face is the problem of how to hold on to today's short period of time.

The protagonist soon learns that the defense line of the Divine Envoy King's army is actually losing ground in the street battle.

Although the defenders used razor tactics to kill thousands of enemies, and the killing effect was considerable, due to the continuous infection of the silk parasite bacteria that were unexpected, the defenders who were very scarce in troops also lost hundreds of troops, which was equivalent to seventy-eighth of the troops of the first line in the short period of battle.

Moreover, compared to the numerous enemies outside the ant nest, which are still pouring in like mountains and seas, the battle damage of the Divine Envoy King Legion is difficult to replenish in a short period of time, and it will take nearly a month for the next wave of reinforcements to arrive.

Following the defeat in the air battle, the Divine King's legion was again threatened in land warfare.

The protagonist calculates that with the strength of the Fourth Legion, it can barely support until the sun goes down, and it will be enough to wait for the enemy to retreat automatically, but then the Fourth Legion will basically be disabled and lose most of its combat effectiveness.

This is a major blow to the protagonist of the parasitic forces who are determined to sweep away the entire swamp.

I didn't expect that the swamp strategy plan that I was aiming to win at the beginning would encounter such a big resistance just when I took the second step (the first step was to establish [Swamp City] as a base for advancement).

The troops at the front were still in a bitter battle, and the Fourth Army was in an unprecedented crisis.
